4 is a number , numeral and glyph. it is the natural number following 3 and preceding 5
Answer:
x = 3
Step-by-step explanation:
The diagonals of a rhombus bisect each other at right angles, thus
BE = ED, that is
4x + 2 = 3x + 5 ( subtract 3x from both sides )
x + 2 = 5 ( subtract 2 from both sides )
x = 3
Answer:
n^2 + 3.
Step-by-step explanation:
4 7 12 19
Differences are 3 5 7 so this a quadratic sequence.
2nd difference = 2 2
So the first part of the expression is n^2
Terms: 4 7 12 19
n^2 1 4 9 16
Difference = 3 3 3 3 3
So the answer is n^2 + 3.
The volume of a rectangular prism is W*H*L
W=Width
L=Length
H+Height
We know that 16=W*H*L
We know the Length and the height are equal because they are both 2 meters less than the width, so lets rewrite this and add an equation
16=W*H^2 (this is height squared because we changed Length to Height since they are equal)
And add the equation
W-2=H
Lets plug in this Height value into our equation
16=W*(W-2)^2
16=W*(W^2-4W+4)
16=W^3-4W^2+4W
W^3-4W^2+4W-16=0
Im not sure how it expects you to solve this without a graphing calculator, maybe someone can clarify this, but the only possible root at this point is W=4
With this we know L and H=2
So the dimensions are
4x2x2
Answer:
No
Step-by-step explanation:
Positives cannot point at negatives I think.
